IMPROVEMENT IN `VAPORBURNERS.

Specification forming part of Letters Patent No. 188,906, dated March 13, 1877; application filed l November 1e, 1876.

To all whom it 'may concern y Be it 'known that I, JONAS G. HOBERT,-of Syracuse, in the county-of `Onondaga and State of New York, have invented a new and Improved Vapor-Burner, ot' which the following is a specification In the accompanying drawing, Figure Il represents a horizontal section of Inyimproved 'vapor-burner on line c c, Fig. 2 5 Figl.`2, a vertical central section of the same; Fig. 3, a detail section of theV stem of the supply-valve; Fig. 4, a detail vertiealtransverse section on cleaned and adjusted, and very economical in use. v

The invention consists of a vapor-burner,

, arranged with a notched or grooved stem ot' the supply-valve, that may be readily removed for being4 cleaned of` gummy sediments; y also of a heating-tube' with regulatingvalvaa detachable shield o r inclosing tubefor admitting -the cleaningot the heating and main tubes,

and of an alcohol-dish, secured vvertically be low,and centrally totheiaXis of theshield'.

In the drawing, Arrepresentsjthe uppervde-A tachable burnertube, and B the lower burnertube, to which gasoline or any other light hydrocarbon is supplied by a conducting main tube, C, placed Vat right angles tok thel lower burner-tube. The upper buruer-tube Ais fitted A, to a seat, a, of the lower tube B, and is retained,

by a recess and lip, b, in position thereon. `[Ehe gasoline vaporsA enter to the upper burnertube through a smallaperture, d, ot' thelower tube B, and minglewith atmospheric air entering throughside holes d', so as to be fully burned up.` Theijexiaaperture d lis kept clean by means of a valve-stem, D, with ,tapering and channeled or grooved en d, that tits intol aperture d, and kadmits the passage of the vapors through the channels or grooves e of the stem, as shownin detail in Fig. 5; `The `lower part of rthevalve-stem Dis secured to a screw-plug, D', that screws into-the bottom part of the lower burner-tube. `The screwplug D serves also to secure, by means of a collar, f, the alcohol-dish E into position.

The grooves of the conical valve-stein are intended to give direction to the ilow of gas, so that it will go directly up to the aperture ofV the burnertube without striking the sides of the tube, thus producing a direct, free, and forcible exit, and giving a stron ger and better light than when the current of gas impinges against the inside. of the tube and causes eddies in the current. A

The grooves, which are arranged in pairstwo, four, or moreare placed directly opposite each other, so that when the currents meet they will counteract upon each other, and thus tend in upward direction.

The grooves are intended to be made of proper size to admit the ow of just suilicient gas to give a llame of certain size, when the valve is snugly screwed into its place in the seat a. This enables an unskilled person to take it out and clean it when necessary, and put it back to its proper place by screwing it to its seat.

The burner is readily cleaned by detaching the stem D, and clearing the same of any adhering gulnmy sediments or dirt. The supply-aperture is thus, by means ot' the stem, prevented from choking without introducing a pin or tool, and enlarging thereby the supply-aperture, so as to spoil the burner and necessitate the repairing of the same.

The liquid-supply tube C is flattened at the top and bottom, for being more fully exposed to the heating side jets of a tube, F, arranged below the supply-tube, at right angles to the lower burner-section. The heating tube F communicates by a couicalaperture with the lower part B of the burner7 which aperture is opened or closed by the conical end of a stemvalve, Ef, that is adjusted by a screw-plug, g, in the outer end of the heatingtube.

The supply of vapors to the heating-tube may be regulated, increased, or interrupted by the stem-valve E', which furnishes a reliable device ior controlling the light of the vapor-burner. The gas-jets issue through .side apertures of the heating-tube, and heat the supply-tube, so as to change the gasoline into vapors.

For lighting the burner, the heating-tube is rst heated up by the alcohol-dish E, which is secured vertically below the inclosing shield or tube G, and nearly centrally to the axis of the same.

The diameter of the alcohol-dish is about equal to that of' the shield G, which produces a more finished appearance of the burner, as the alcohol-dish looks like a cap at the lower part of the same.

rlrhe entire heating capacity of the alcohol is, by this arrangement of the dish, thrown on the supply-tube C, so as to produce the gasoline vapors, and light the same when they issue from the holes of the heati 11g-tube. The

vapor-jets heat then the supply-tubo, admitting thus the lighting of the burner in quicker manner than heretofore, where the alcoholdish has been placed more or less outside of the shield.

The shield G is secured, in detachable manner, to the burner and supply tubes by being tted at the open side exactly to the burnertubes A B, and by holes to the supply and heating tubes. It is tightly fastened in position by a binding-screw sleeve, h, of the conducting-tube G', which may be provided with suitable strainers and absorben ts for admitting only the passage oi' pure gasoline.

By unscrewing the binding-sleeve, and removing the burner from the conducting-tube, the shield may be readily detached, and thereby the heating and supply tubes conveniently cleaned ot' all impurities. This forms an important feature of my burner, as thereby everv part of' it may be fully brought within view for cleaning and repairing, if necessary.

The main advantage of the burner consists, therefore, in the ready access to, and cleaning of', the different parts, in the time gained in lighting the same, which is of considerable importance in street and other lamps, and in the saving of gasolineobtained in the heating of the supply-tube by the direct connection ofthe heating-tube with the lower burner-tube.

Having thus described my invention,Iclain1 as new and desire to secure by Letters Patent- 1. The combination of the exit-aperture of a vapor-burner with a grooved or channeled and conical valve-stem, substantially as and for the purpose set forth.

2. The combination of the lower burnertube with a screw-plug having an enlarged shoulder or collar, and an Valcohol-dish placed vertically below the inclosing tube or shield,

of the burner, substantially as specified.

3. The combination of the attened supplytube Yand lower burner-tube with a heatingtube, placed vertically below the supply-tube, and having an adjustable stem-valve for regulating the gas-jets of the heating-tube, substantially as specified. r
